Patent GB-2035957-A (GB)
Title: Improvements in and relating to devices for supporting growing plants
IPC: A01G9/12
Filed: 1979-11-15
Abstract: A spool for use in "layering" plants has two flanges (5, 6) one of which (6) is larger and heavier than the other (5) and has cord locking slots (8, 8a) extending inwardly from its periphery (9). In use, the spool is wound with cord 21 and mounted on a horizontal support wire (22) above a plant (not shown). The spool tilts to one side on the wire (22) with the flange (6) lowermost. Cord (21) is passed from the spool, about the support wire (22) through a cord locking slot (8) and attached to a plant below. The spool is thereby maintained on the wire (22) and cord (21) is prevented from unwinding. When required, at intervals during the growing season, the spool may be rolled backwards (arrow A) to release the cord (21) from the slot (8), then rolled forward to pay out the required amount of cord (21), and then the cord (21) is reengaged in a slot (8). <IMAGE>

Title: A hydraulic valve for the control of well safety valves
IPC: E21B34/16
Filed: 1980-03-10
Abstract: A hydraulic valve operating circuit for providing positive opening and closing of a downhole safety valve includes shut-off valves which prevent leakage of fuel to the outside environment if a leak should occur in the hydraulic lines which are connected to the hydraulic actuator of the downhole safety valve. A hydraulic control line is connected to the actuator of the safety valve through a normally-closed shut-off valve and the hydraulic control line is also connected to the actuator of the shut-off valve to hold both the shut-off valve and the downhole safety valve open when the hydraulic line is pressurized. Another valve moves to a position to direct the flow of fluid from the safety valve to an accumulator when the pressure in the control line falls below a predetermined value to ensure that the downhole safety valve will close properly. The accumulator and the actuator control valves are provided by a single gate valve comprising a base 102 having inlets B, C and outlets 28, 29, and a gate 121 having ports 122, 123 and a passageway 126, the gate being movable between a first position, in which inlets B, C are connected to respective outlets 29, 28 via respective ports 123, 122 and a second position in which outlets 28, 29 are interconnected by passageway 126. <IMAGE>

Title: Printing head and printing device
IPC: B41J3/01
Filed: 1980-05-13
Abstract: A printing head comprises an array of cells (19) each containing an interchangeable type for printing a respective character, the types being slideable relative to the cells from a rest position to an impression position, the arrangement being such that return of each type towards its rest position from its impression position is effected by its resiliently rebounding from the platen (11). A print hammer (20) propels the types against the platen. A linear motor (13) moves the trolley (14) relative to the platen (11). The position of the trolley may be under closed loop control. The printing head may be movably mounted on the trolley for movement in the horizontal and/or vertical directions, by one or more linear motors and optionally with closed loop positional control. <IMAGE>
Patent GB-2054401-A (GB)
Title: Counter-current fluid-fluid exchange apparatus
IPC: B01D11/04
Filed: 1980-06-13
Abstract: A counter-current exchange column is sub-divided by horizontal partitions, a series of identical stages each comprising a mixing zone and a separating zone. In the mixing zone, agitators thoroughly blend the phases yet impart no vertical motion thereto; by reason of their different specific weight, the phases separate in the separating zone. The mixing and separating zone of each stage are connected via ports (9) in the partition between them. The mixing zones of adjacent stages are connected by tubes (10, 11) which pass through the separating zones (3, 8) disposed between them and the partitions separating the adjacent stages. The mixing zone of each stage is connected to the separating zone next to it (i.e. in an adjacent stage) via a connecting element (12, 13) projecting vertically into the separating zone, having a flow path which reverses direction after the fashion of a siphon. In operation, the heavier phase flows through the tubes which connect the mixing zones of adjacent stages, while the lighter phase flows through the connecting elements which connect the adjacently disposed separating and mixing zones (3, 7) of adjacent stages. The structurally simple column arrangement avoids any retro-mixing between stages. <IMAGE>

Title: Attitude control system for spacecraft utilizing the thruster plume
IPC: B64G1/26
Filed: 1980-08-15
Abstract: An attitude control system for a spacecraft (10) having thrusters (21-24) utilizes the exhaust plume of the thrusters for attitude control. The system is based on a configuration in which the thruster exhaust plume effect, caused for instance by the thruster plume impinging on a surface of a solar array (14) which is included in the spacecraft, is advantageously made beneficial by orienting the thrusters to achieve improved attitude control. At least one of the thrusters is canted so that the thruster control torque (Tc), if any, aids rather than opposes the torque created by the impingement of the thruster plume force(F'p). <IMAGE>

Title: Improvements in or relating to guns
Inventor: WHEELER REGINALD GODFREY
IPC: F41G3/32
Filed: 1982-04-17
Abstract: In a system for detecting errors in the boreline direction in a gun having a relatively long barrel, an optical sensor 2U is arranged to view the muzzle 11 of a gun barrel 1 preferably via the sight (periscope) mirror 6 associated with an optical aiming sight of the gun. The optical sensor is positioned closely adjacent to the optical aiming sight so as to enable all position errors between the aiming sight and the muzzle to be removed. The optical sensor is preferably a solid state two dimensional device scanned in a television like raster pattern, and window signals are inserted into selected line scans so that the actual position of the muzzle can be very precisely compared with its required position. Any departures from the required position are compensated by feeding correction signals into the optical aiming sight to shift the gunner's aiming mark accordingly. <IMAGE>

Title: Supporting frame joints
Inventor: KORTH BERND
IPC: F16B12/28
Filed: 1982-04-23
Abstract: Cross-beams, located between column elements of the support frame, contain, at their beam-ends, clamping members which are mounted inside a cavity in the cross-beam body in a manner permitting displacement in the longitudinal direction of the cross-beam, and are capable of being brought into, and out of, engagement with the column elements. These clamping members are expanding elements, coupled together and guided so that they move in pairs, their head part, which engages into the column element, being provided with clamping means and centering means, and being capable of being pushed completely back into the cross-beam cavity. The expanding elements can be forced apart from each other, in a parallel relationship, perpendicularly to the longitudinal axis of the cross-beam, by means of a socket-head screw which can be operated from the outside of the cross-beam. The design of the clamping members on the cross-beams permits the installation of cross-beams between columns which are already fixed, without dismantling any part whatsoever.
